Network Protocol and Architecture
This chapter is about protocols, the rules by which digital data networks operate. In the earlier chapters we carefully developed the notion of a physical data link composed of transmission lines and modems, and then considered some typical rules of operation for the physical level (RS-232C, RS-449) and for the data link level (BSC, Poll/Select, DDCMP, SDLC). In the preceding two chapters we have analogously developed the notion of a physical data network composed of data links and network components. Now in this chapter we shall consider the rules of operation, i.e., protocols, for entire networks. However, before delving into the myriad details of the various formal network protocols, it will be helpful first to establish some basic intuition about protocol in general.
